* Name: syslog_initialize
|
|
*
|
|
* Description:
|
|
* One power up, the SYSLOG facility is non-existent or limited to very
|
|
* low-level output. This function is called later in the initialization
|
|
* sequence after full driver support has been initialized. It installs
|
|
* the configured SYSLOG drivers and enables full SYSLOGing capability.
|
|
*
|
|
* This function performs these basic operations:
|
|
*
|
|
* - Initialize the SYSLOG device
|
|
* - Call syslog_channel() to begin using that device.
|
|
*
|
|
* If CONFIG_ARCH_SYSLOG is selected, then the architecture-specifica
|
|
* logic will provide its own SYSLOG device initialize which must include
|
|
* as a minimum a call to syslog_channel() to use the device.
|
|
*
|
|
* Input Parameters:
|
|
* phase - One of {SYSLOG_INIT_EARLY, SYSLOG_INIT_LATE}
|
|
*
|
|
* Returned Value:
|
|
* Zero (OK) is returned on success; a negated errno value is returned on
|
|
* any failure.
|
|
*
